Characterization of physicochemical factors and volatile fatty acids during incubation. (A) Characterization of physicochemical factors. (B) Characterization of volatile fatty acids (VFAs). Orange and blue represent the control and SRB-inhibited treatment groups, respectively. D00, D05, D12, D21, and D30 on the x axis represent 0, 5, 12, 21, and 30 days of incubation. Error bars represent the standard deviation. The results of ANOVA with Turkey’s HSD tests from days 12 to 30 are marked in the gray area.
